SAFETY GUARD.

Application filed July 14,

This invention relates to a guard for a cross cut saw, the generalobject of the invention being to provide means whereby the guard willautomatically cover the saw when the saw has been moved to the front ofthe apparatus, the weight on the saw operating means for lifting theguard when the saw is in its inoperative position.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, il- I lustrated in the accompanyingdrawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which c Figure1 is an elevation showing the guard in lowered position.

Figure 2 is a similar View with the guard in raised position. I

Figure 3 is a plan view.

Figure 4 is a perspective view of the parts at the rear end of theguard.

In these views, 1 indicates the saw table which includes a slide for thebearing blocks 2 for the saw arbor 3, the saw being shown at 4. A lever5 is pivoted to one of the blocks 2 at its upper end and is pivotallyconnected to a part of the table at its lower end, as shown at 6. Aweighted arm 7 is fastened to this lever and acts to hold the parts withthe saw in its rear and inoperative position. The foot lever 8 ispivotally connected with a part of the frame, as shown at 9, and a link10 connects the lever with the lever 5 so that when the foot lever isde-,

pressed, it will swing the parts forwardly, as shown in Figure 1, sothat the saw will cut a log or other object placed on the table.

In carrying out my invention, I provide a casing 11 which is carried bya pair ofarms 12, these arms having their rear ends provided withdepending portions which are pivoted to a support 13 fastened to thetable. These parts are so arranged. that the casing will normally assumea position over the saw,

when the same is in its forward position, under the action of gravity.The front end of the casing is provided with a strip 14 of rubber or thelike which will engage the front end of the table. A rearwardlyextending arm 15 is fastened to one of the arms 12 and carries a weight16 which acts to counterbalance the casing 11. A bell crank 17 ispivoted to the rear part of the table and a link 18 connects said bellcrank with an arm 19 which is connected with one of the arms 12. AnL-shaped arm 20 is pivoted to the bell crank lever and extendsdownwardly, with its short part extending under the table, where it isprovided with a roller 21 which will be engaged by the weight 22 of thearm 7 when the saw is in its rearward and inoperative position. Thus theweight, acting on the roller 21, will depress the member 20 and causethe bell crank to move the link to the rear and raise the casing 11, asshown in Figure 2, so that a log or other object can be placed on thetable in the path of the saw. Then when the foot lever is, depressed tomove the saw forwardly to cut the log, the weight 22, movin off the roll21, will permit the casing 11 to rop and cover the saw.

A small roller 23, carried by the arms 24 at the rear of the table,guides the member 20 in its vertical movement.

Thus I have provided simple means for guarding a saw so that there is nodanger of the operator being injured by placing a part of his body inthe path of the saw, during the sawing operation.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionandin the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claim.

What I claim is In combination with a cross cut saw including its table,a Weight for holding the saw normally at-the rear ofthe table and thepedal lever for moving the saw to the front of the table, a guardcasing, arms connected ed from the top of the table, the casing normallycovering the front end of the path of the saw, a bell crank pivoted tothe table at the rear thereof, a link connecting one arm of the bellcrank with a part on the rear of one of the arms, 9.- depending memberpivoted to the other arm of the bell crank and having a part extendingunder the table and a roller on said part engaged by the Weight Intestimony whereof I afliX my signature JAMES WOLF.
